SPRING NUT LOCKING DEVICE FOR RAIL JOINTS Fi led Sept. 20.- 1929 shall have been completelyadjusted all acci-v dental turning or loosening of the nuts, usually caused by the excessive jarring that emai be maintained i nates from the rolling stock passing over the joints, will be prevented, and the bolts will n their proper transverse alinement.

It will also be evident that in the event that a splice bar. should be accidentally broken, this type of locking device possessing unusual strength will readily serve to retain I the rails in proper alineinent until the break is I i so discovered and repaired, thereby preventing 5 what is known as lipp'ing ofthe track rails which isliable to cause a derailment of the r'ollin'g'stock. It will be understood that any required or through the end portions of the track rails "and through the splice bars, and that'any suitouter ends.

desired nun'i'ber of holes may be formed faceofeach of said members, a longitudinal outwardly and centrally disposed extension for m edon eachouter side, and a bolt opening ,"formed therethrou'gh near each of its HARRY to. NORWOOD.

able number-bf bolts and securing nuts may be employed in the proper locking and securing of the track rail joints.

' Having thus described my invention what I claim and desire tdsecure by Letters '-Pat ent is:

i 1.' A spring 'nut locking device for rail joints, comprising a single piece of spring steel horizontally'foldedupon itself at its centralportion to form two oppositely disposed horizontalmembers, each of said members beingfformed with a longitudinally dis- 7 posedfrecess oiniitscentral inner face extend i,

ing throughout its "length.

' 2. A spring nut locking device for 'rail' joints formed from "a single H-shaped piece of inetal, said Hie-shaped piece being doubled horizontally upon itself at its central portiontdforrn a pair of oppositely disposed horizontal members,'each member having a longitudinallydisposed recess formed ceni trally in ea'ch'inner face throughout its length- 3. A spring fnut locking device formed from asingle piece of high grade spring", 1 steel folded horizontally 'upon itselfat its central portion forming a horizontally disposed member' at each opposite side of its central foldedportion, each member j 7 provided with a longitudinally centrally and i being oppositely disposed recess and an outward ex tension formed 'in each of its upright portions.

' [4. A springv nut locking device for rail joints formed from a singleH-shap'ed piece spring steel horizontally foldedcentral 1y upon itself forming a horizontallydisposedi extension at each side of its central portion, each extensionbeing provided with i a longitudinally and centrally disposed recess"formed in-itsinner face at each'side the'reo fyand" an" outward longitudinal eXtILe i, sion formed at each opposite side thereof ex 7 l :06 tending throughout its length.
